linux中mysql授权问题

mysql> grant all privileges on *.* to ‘root‘@‘%‘;
ERROR 1410 (42000): You are not allowed to create a user with GRANT
mysql> grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘root‘ with grant option;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘identified by ‘root‘ with grant option‘ at line 1

正确的写法是先创建用户
CREATE USER ‘root‘@‘%‘ IDENTIFIED BY ‘Hadoop3!‘;
再给用户授权
grant all privileges on *.* to ‘root‘@‘%‘ ;
